An enterprise is exploring a new business opportunity. Which of the following is the BEST way to help ensure related IT projects deliver the business requirements?

Hiring a business consultant to manage projects might bring expertise but doesn't inherently guarantee business requirements are met without specific oversight mechanisms like sign-offs.

Developing a policy to enforce processes and procedures is general governance and doesn't directly ensure specific project deliverables meet business requirements without active business involvement.

Implementing stage-gate reviews that require formal business sign-off at critical project milestones is the best way to ensure IT projects deliver business requirements. This mechanism ensures continuous alignment between project deliverables and business needs, forces communication, and provides explicit approval from business stakeholders before progressing, thereby reducing the risk of misalignment or scope creep.

Focusing on maturing processes and developing procedures is a foundational improvement, but it doesn't, by itself, guarantee that *this specific project* will deliver the intended business outcomes without direct business review and approval.
